Trident Park is a stunning large-scale regeneration project, which involved the conversion of Farson’s old bottling factory and stores into a modern office campus. The existing facade of the building, as well as its prestigious entrance and board room were retained, whist the remaining structure of the building was dismantled and rebuilt to house over 15,000 sqm of office space, conference facilities and a separate above ground car park block with a capacity of 700 cars, which are in turn connected via open air walk ways and surrounded by over 3,000 sqm of landscaped courtyards and gardens.
The project was designed to meet the strictest of environmental standards with the aim of achieving BREEAM Excellent certification and minimising the building’s carbon footprint.
Panta’s involvement began early on in the construction phase of the project as it was entrusted with the installation of the building’s Thermally Activated Building Systems (TABS), which is a first of its kind on the island. The system involves circulation of chilled or heating water through 100,000m of PEX pipework which is embedded in the concrete slabs of the structure. The system activates the thermal mass of the structure and is designed to cater for the basic cooling and heating loads of the building, thus resulting in a constant and comfortable indoor climate within the office space, whilst achieving higher levels of energy efficiency and lower operational costs.
Other systems which formed part Panta’s scope of works included the following:
Mechanical and HVAC systems
- Supply and installation of HVAC systems comprising of 6 packaged air-cooled reversible heat pumps, 13 double thermal wheel air handling units and Fabrication and installation of over 10,000m2 pre-insulated ductwork.
- Installation of chilled water and plumbing infrastructure comprising of over 9,000m of insulated black steel pipework and 2,000m insulated PPR pipework.
- Supply and installation of:
- 41 TABs circulating pumps
- 46 Chilled / Heating pumps
- 14 Domestic cold water / hot water circulating pumps
- Laying of 100, 000m PEX TABs pipework in concrete slabs.
- Supply and installation of hot water generation systems comprising of 10 Domestic hot water heat pumps and 6 5000L buffer tanks.
- Firefighting hose reel system.
- Supply and installation of 3 Main electrical panels, 17 sub-distribution boards, 114 distribution boards, and 42 consumer units.
- Supply and installation of electrical infrastructure comprising of 29,000m of armoured cables, 40,000m Single core cables, 3,000m cable trays and 3,500 cable baskets.
- Supply and installation of 2 600kVA standby generator sets.
- Small lighting and power installations.
- Fire alarm systems
Building management system (BMS)
The BMS controls and monitors all mechanical and electrical equipment installed within the project and comprises of the following:
- Ventilation systems
- 400 field devices installed across ventilation ductwork and AHUs.
- 11 Extract Fans
- 41 VAV boxes – Control of fresh air supply
- Heating & Cooling system
- Interfacing with 6 Chillers
- Main Chilled and Heating Water Pumps – pressure control
- 3 – Heating
- 3 – Cooling
- 41 – Pressure sensors
- 22 – Temperature sensors
- Chilled/Heating block pumps
- 14 duty/standy – pressure control
- Plumbing system
- 3 Pressure Booster sets
- 12 Recirculation pumps
- Chlorine Dosing System
- 5 Sump Pumps
- 10 Heat Pumps
- Thermally Activated Building System (TABS)
- Since the TABS has a relatively slow response time, the BMS was designed in such a way so as to implement a self learning algorithim in order to operate heating and cooling within the office areas in the most efficient way. Initially the BMS is fed with a schedule of expectant loads, following which the system automatically starts to adjust the required timings in order to reach the expected temperature. This includes the following:
- 581 On/Off valves
- 41 circulating pumps
- 41 modulating valves
- 41 immersion temperature sensors
- 208 wireless (enocean protocol) space temperature and humidity sensors
- 176 wireless (enocean) surface temperature sensors
- The lighting system is also integrated with the BMS, which consists of DALI system, traditional lighting and as well as wireless switches (enocean protocol).
- 70 IP servers all running concurrently and communicating with each other.
- Panta created in house controls for TABS system
- Numerous AI enabled algorithms running for optimized comfort and efficient energy consumption
The BMS also features interfacing of electrical meters, water meters and thermal meters which allows the facilities management to monitor energy consumption. Moreover the BMS is composed of user friendly graphics complete with the scheduling and trending of the the equipment and field devices mentioned.
